Before the Ries impact link was established, and outside mainstream science since, many ideas have been proposed about where Moldavite comes from and what it means. This page collects them, with an honest evidence check for each.

Mainstream science view: Moldavite is melted Earth sediment ejected by the Ries asteroid impact ~14.8 million years ago. See [Hard Science](https://moldavitegems.com/science.html).

## Theories

### Lunar volcanism former scientific hypothesis

From the 1950s to the 1990s some respected scientists, notably John O'Keefe, argued tektites were ejected from volcanoes on the Moon.

**Evidence check:** Apollo samples and isotope chemistry do not match; Moldavite matches Ries-area sediments. Largely abandoned.

### Terrestrial volcanic glass historical

Early naturalists thought Moldavite was volcanic obsidian or a slag.

**Evidence check:** Too dry, with lechatelierite and no nearby volcanic source. Rejected.

### Man-made glass historical

Some 19th-century observers suspected ancient glassworks.

**Evidence check:** Found in undisturbed sediments millions of years old, and used in the Stone Age. Rejected.

### Separate comet or airburst fringe

Proposals that Moldavite came from a distinct cosmic event rather than the Ries crater.

**Evidence check:** Ages and chemistry match the Ries impact closely. Unsupported.

### The Holy Grail legend

A popular modern legend says the Grail was carved from, or set with, an emerald that fell from Lucifer's crown, identified by some as Moldavite.

**Evidence check:** A modern New Age reading of medieval Grail stories (where the Grail is sometimes a stone). No historical link to Moldavite.

### Extraterrestrial & "starseed" ideas spiritual belief

Beliefs that Moldavite carries off-world energy or connects people to star beings or Atlantis.

**Evidence check:** Not testable scientifically; Moldavite is made of Earth material. See [Energetic Properties](https://moldavitegems.com/energetic-properties.html).

## Open questions scientists still discuss

- Whether the Steinheim crater formed at exactly the same moment as the Ries.
- The exact size and angle of the impactor, and why melt went so far in one direction.
- How much Moldavite originally fell, and how much remains buried.
